Sinergy Flow develops advanced redox flow batteries, providing a modular and scalable solution for low-cost, sustainable, and multi-day energy storage. The company's technology focuses on utilizing abundant and low-cost materials, aligning with principles of the circular economy to create environmentally conscious battery systems. Their approach addresses the growing demand for efficient and long-duration energy storage.
The company was founded in 2022 by Alessandra Accogli, Gabriele Panzeri, and Matteo Salerno, establishing its base in Milan, Italy. The founders initiated Sinergy Flow based on the insight that the energy sector urgently requires innovative deep technology solutions for sustainable energy storage, moving away from traditional, resource-intensive battery chemistries.
Sinergy Flow's products target various sectors requiring long-duration energy storage, from renewable energy integration to grid stabilization. The company envisions a future where energy storage is not only effective but also inherently sustainable and environmentally responsible. Their mission is to facilitate a cleaner energy transition through their innovative battery solutions.

Sinergy Flow is a Milan-based DeepTech startup founded in 2022 that develops low-cost, sustainable redox flow batteries (RFBs) for long-duration energy storage (8-20+ hours), enabling up to 90% renewable energy penetration in electrical systems.[1][2][3] The company serves energy providers, utilities, and communities seeking scalable solutions for grid stability and decarbonization, solving intermittency issues with renewables by using abundant, recyclable materials like sulfur from petrochemical byproducts, aligned with circular economy principles.[1][2][4] It has raised €1.8 million in seed funding from 360 Capital Partners and Cassa Depositi e Prestiti (CDP Ventures), achieving early traction through awards and operational headquarters setup.[1][3]
Sinergy Flow emerged from doctoral research at Politecnico di Milano, where CEO Alessandra Accogli—PhD in Materials Engineering and an expert in RFB development—collaborated with CTO Gabriele Panzeri (PhD Materials Engineering, battery R&D leader) and COO Matteo Salerno (PhD Materials Engineering and Nanotech, energy storage operations specialist).[1][2][3] The idea crystallized during the Switch2Product Challenge at Politecnico, where their innovative chemistry won for its circular economy focus, launching the startup.[3] Pivotal early wins included Best Italian Startup (Everis Awards 2021, Premio Nazionale Innovazione 2021), Best Cleantech & Energy Startup (Startcup Lombardia 2021), IP Awards 2021, and ENI Awards 2022, drawing investor interest and culminating in a €1.8M seed round in November 2022.[3]
Sinergy Flow rides the global surge in renewable energy storage amid the energy transition, addressing grid intermittency as solar/wind scale to meet net-zero goals.[2][3][6] Timing aligns with EU Green Deal pressures and post-2022 energy crises, favoring independent, low-cost tech over import-dependent lithium; sulfur's waste-origin disrupts supply chains, boosting energy communities' autonomy.[2][4] It influences Europe's cleantech ecosystem as an Italian success story, inspiring waste-to-value models and drawing corporate/investor attention in climatetech.[3][6]
Sinergy Flow is poised for pilot deployments and Series A scaling, leveraging its seed capital for prototype validation and industrial partnerships to capture the booming long-duration storage market (projected trillions globally).[1][3] Trends like rising renewables (targeting 90% penetration) and circular economy mandates will propel growth, potentially positioning it as a European leader in sustainable batteries amid sulfur's untapped potential.[2][4] Its influence may expand through exports and ecosystem collaborations, transforming Italy's DeepTech footprint and accelerating decarbonization—echoing its origins in academic innovation to unlock clean energy's full promise.[3][6]
Sinergy Flow has raised $2.0M across 1 funding round. Most recently, it raised $2.0M Seed in November 2022.
